Gay, a former LSU cornerback, turned 30 this month and should be entering the prime of his career. Instead, Gay told the Boston Herald he is too debilitated to play football because of repeated concussions and is retired after seven NFL seasons.

“I can’t play anymore. I wish I could, but I’m still having symptoms from concussions,” Gay told the Herald. “I wanted to try again, but I can’t really do anything. Hard, physical activities, I get headaches and nauseous and dizzy and stuff. I’d still like a chance in the NFL, but it’s not worth it.”

Gay could not say how many concussions he had during his career, telling the newspaper “I don’t know. A million."

He last played in 2010 with the New Orleans Saints after signing a four-year, $17.6 million deal in 2008.
